bad experience on mango flight

I'm so disappointed with Mango Airline after taking it from Port Elizabeth to Johannesburg on the 4th Nov 2019 at Departure time17:50, Flight JE 548. The flight not stable on numerous occasions while we were on our to JHB, 3 times with thought it was gonna crush and to top it all the landing terrifying. they didn't apologies it was as if its normal while the heard people screaming on 3 occasions during the flight, now i'm scared of flying after what i have experienced on the latter flight. i have traveled the world and it was my first time experiencing such trauma
